Abstract

In the satellite configuration, one or more receiver satellites and/or transmitter satellites and/or transceiver satellites with horizontal across track displacement with the same or different amplitudes are provided. The satellites are at the same orbital height and move with the same speed. A horizontal along track distance can be set between the individual satellites. This remains constant independent of the orbital position.
